lly invention has reference to 'commer application for Letters Patent ofthe United States filed May 19, 1925, SerialNo. 81269. Thepresent=invention seeks to improve; the manner of consti'uctionandarrangement of such signs.

One of the objects thereof is to provide a sheet metal frame or mouldingfor the' sign which is formed of asingle sheet of metal, bent into thedesired form, by which construction a frame of great strength may.

letter in which is beveled or otherwise turned out of the plane of themain sheet. This not only strengthens the edge of the plate, but when abacking plate for the letters is used, as shown in said formerapplicatlon, the turned edge of the letter bears against the. backingplate, forming a more rigid structure, and preventing anyrattling soundwhich might result from a loose contact of such parts. in some cases toform a flange on the edge of the letter by means of a strip fastened atan angle therewith by soldering or similar method, butthis method isaslow and expensive one.

The production of the letters in the manner mentioned in a simple and"inexpensive manner is made possible by means of a machine designedspecially tor the purpose, and

the subject of a companion application for Letters Patent of the UnitedStates; ]By the use of this machine any style of letter or othercharacter can be cut and formed by a,

continuous operation, or operations It has been the custom to cut out aletter with a cutting tool, comprising suitable dies and cutters, buteach one. has been limited to the production of a singleletter', and aspecial type oit'letter, whereas in the use of said machine any desiredstyle can be reproduced.

The above named, and other features and advantages of the invention willmore fully appeartrom the following specification, ret? 'erence beinghad to the accompanying drawings, in which-;

i Fig; 2 is a" cross se'ction on' the broken line 2 20f Figl1;-' 1 Fig;-3 is a cross-section ofth'emoulding 1, enlarged. f 3 f The referencenumber 1 indicates the up- Pfmouldingofa sheet-metal frame,- 2 the Ilower moulding, and 3 one of the end pieces, properly joined with, thefirst-named: sections. The lower moulding is formed with a channel 1,for the support of the lower edges of any desired number of letterplates- 5, in rear of which is shown a backing plate 6, of frosted glassor similar material,

also supported in the channel'4." The upper edges otthe-plates 5 and'6are held in a channel 7 formed on the inner side of the uppermoulding 1. The-letters are formed bycutt-ing the same from the plate 5,as in dicated by the letter E in Fig. 1, the edges of theletter beingbent inwardly at an-angle of approximately forty-five degrees, as

shown at '8, the inturned edges bearing against the outerface of theplate 6, and assisting in providmg the rigid construc-.

tion hereinbefore mentioned. 7 The mouldings are each provided backplate 9, bent forwardly into a cornice comprising a straight band '11and curved,

portion 12, ending in a panel'13, formed at its lower edge into alooplt. In the case with at,

ofthe moulding 1 this loop, is'continued into the channel 7, the inneredge 15 of which'is turnedv upwardly. The edge 16 of the plate -9 isalso turned upwardly, the turned edge thereof being enclosedwithin theloop 14,

and. adding strength to thejoint formed I thereby. I

' All of the parts above mentioned are integrally formed, suchconstruction doing away with the necessity of riveting or otherwiseconnecting a number of separate parts,

as is now the custom;

The moulding 2 is formed moulding 1, except that the channel 7 is givena greater depth than that of the chan similarly to the l nel 1, so thatthe plates 5 and 6 can'be. first into the channel 41, withoutpossibility of their release except by a reversal of the. operation.

The edge of the letters in the letterpl'ates can be bent so as toproject at any desired angle with the main plate, including a rightangle, or they can be" turned into ahead or other formation out of linewith said plate. Thesebevels and other formations inserted in thechannel 7, and then lowered are always produced integrally with v theplate, by a comparatively simpleoperation,

back plate having its lower edge turned up- I wardly against itself,anda cornice formed wintegrallyewith said back plate, andhaving I saidback 'back plate and cornice formed integrally itsilgwer edge rolledround the lower edge'of plate. r 1 I 2.-Ai sheet metal frame, 7.comprising a What I claim, and desire to secure by therewith, andhavingits lower edge rolled round the lower edge of said back. late, and
